SPECIFICATION forming partof Letters Patent` No. 278,573, dated May 29,1883.

ApplicationledJanuaryl,1883. (Nomodcl.)

To all whom it may concern:

Be it-known that I, CHARMED. MARK, of Flint, in the county ot'Genesee'and Stateof Michigan, have invented new and usefull,Improvements in Gar-Couplings; and I do hereby declare that the`following is a full, clear, and exact description thereot',.referencebein g' had to the accompanying drawings, which form a part of thisspecitication.

This invention relates to certain improvements in car-couplings; and theinvention consists in the peculiar construction of the various parts andtheir combination and operation, as more fully hereinafter described.

Figure lis a bottom plan, showing my coupling as attached to a car. Fig.2is a vertical `longitudinal central section'. Fig. 3 is a like view`with the coupling-hook in position when not coupled to an adjoiningcar. Fig. et is an end View. Fig. 5 is a detail.

In the accompanying drawings, which form K a part of this specification,A represents' the two end sections of a draw-bar, and B the centralsection, which connects the inner ends ot' these draw-bars together, oneof such drawbars being provided for each car. j For the purposes of thisconnection the central section, B', is provided with a yoke, a., ateachend, and to the ends ot' each of these yokes `is-secured a socket,b, through which the inner ends ot' the sections A pass, and are securedfrom `being withdrawn by suitable keys,c,-passing through slots in theends of such sectionsA. The free ends ofthe sectionsAterminate in thehooks U.

D represents rectangular iron boxes resting` upon the plates or stirrupsE-one for each end of the car. They are pivotally secured at their rearends, each to its own section Aby the bolt or pin d, the plate E formingthe i'ul- '4o crum, upon which such box D may oscillate as a leveroperates, the spring Flimiting such `movement vertically. The free endsof this rectangular box terminate in an enlarged mouth, Gr, suchenlargement being downward and lateral, as shown in Figs. 2, 3, and 4,and with the upper front portion ot' said mouth closed by theoverhanging part of the casting H, leaving an opening, I, below for thelink to enter. The mouth I is shown distinctly in 5o Fig. 3, and leadsinto an elliptieally-shaped wall of such chamber, allowingthe hook() toengage with it. This hook will always. be in the positioii shown in Fig.2, except when forcibly raised for the purpose of letting the link free,or when raised by the entering link, and, as soon as its cud" passes thehook, the latter will drop and engage with it. vThe peculiar shape ofthehook and the peculiar shape of the chamber J are. such that the link,when in place, will always project horizontally, and be held in thatposition except when the outer end omi' the link may be deliected toenter the coupling of a'n adjoining car which may `be upon a lower orhigher plane. The sections A of the draw-bar are inclosed within therectangular boxes D, and springs K are sleeved upon the inner ends ofthe sections A to perform the functions of springs of the usualcharacter on draw-bars of' the ordinary construction, except that when`the draft is applied at oneend of the car it first exerts its forceupon the coupling at the oppositeend ot' the car, and then upon thespring upon the section ofthe drawbar to which the drat't is applied,thc followers L beingso arranged with reference tothe springs, thesections A, and the points of resistanceM as to allow of this action.The timbers Linder the floor and sills of the car should of course bearranged with special reference to securing these couplings in place 5.but such arrangement is but an ordinary exercise of mechanical skill,requiring no inventive power to do this. `A pin `or link, N, passingthrough a suit-able slot or hole in -the top ot the box D, issecnred toeach of the sections A, near their outer ends, and links or chains O arearranged with suitable levers, l?, so that the hooks may be elevated atwill for the purposes of uncoupling from the top ot' the cnr or from thesides thereof', thereby' preventing the `necessity of entering betweenthe cars for this purpose. I do not desire to contine myself to thisprecise method ofuncoupling, as any ot' the known methods may be adoptedfor this purpose. The rectangular boxes D, which inclose the draw-bar,perform the usual functions of buf- 'ers by their indirect connectionwith the springs K, being formed at the pivotal point d, where suchboxes are connected to the drawbars, and should, from any accident, thehooks C be` broken, an ordinary coupling-pin may be inserted through`the hole in the top through x y 2. In a carco'upling device, and incombinawhich the pin N passes, and thereby form a coupling with thelink, in which case these rectangular buffer-boxeswould become portionsor sections of the draw-bar; but under no other circumstances will they`perform any of the functions of the draw-bar as usually constructed,except the functions of buing. They simply forxn. guides for the linkand draw-bar.

What I claim as my invention is- 1. In combination with the buffer-box Dand fulcrum-plate E, the hooked draw-bar A, having the said box D,pivoted at its rear end thereto, and provided with pin N and liftingdevices, substantially as described, whereby when the draw-bar iselevated the front end of the buer-box is depressed and the couplingreleased', as set forth.
